.SH DESCRIPTION
.I qselect
prints a list of xxQS_NAMExx queue names corresponding to 
selection criteria specified in the
.I qselect
arguments described below. The output of
.I qselect
can be fed into other xxQS_NAMExx commands to apply 
actions on the selected queue sets. For example together with the
\fI\-mqattr\fP option to
.M qconf 1 ,
.I qselect
can be used to modify queue attributes on a set of queues.
.\"
.\"
.SH OPTIONS
.\"
.IP "\fB\-help\fP"
Prints a listing of all options.
.\"
.IP "\fB\-l resource\fP[\fB=value\fP],..."
Defines the resources to be granted by the queues which should be 
included in the queue list output. Matching is performed on 
queues based on non-mutable resource availability information only. 
That means load values are always ignored except the so-called static 
load values (i.e. "arch", "num_proc", "mem_total", "swap_total" and 
"virtual_total") ones. Also consumable utilization is ignored.
If there are multiple -l resource requests they will be concatenated by
a logical AND: a queue needs to offer all resources to be displayed.
.\"
.IP "\fB\-pe pe_name,...\fP"
Includes queues into the output which are attached to at least one of the 
parallel environments enlisted in the comma separated option argument. 
.\"
.IP "\fB\-q wc_queue,...\fP"
Directly specifies the wildcard expression queue list to be included in the output. 
This option usually is only meaningful in conjunction with another
.I qselect
option to extract a subset of queue names from a list given by \fB\-q\fP.
Description of \fIwc_queue\fP can be found in
.M sge_types 1 .
.\"
.IP "\fB\-qs {a|c|d|o|s|u|A|C|D|E|S}\fP"
This option allows to filter for queue instances in certain states.
.\"
.IP "\fB\-U user,...\fP"
Includes the queues to which the specified users have access in the
.I qselect 
output.

.SH "EXAMPLES"
.nf

=====================================================

% qselect -l arch=linux
% qselect -l arch=linux -U andreas,shannon
% qconf -mattr queue h_vmem=1GB `qselect -l arch=linux`

=====================================================

.fi
The first example prints the names of those queues residing on Linux 
machines. The second command in addition restricts the output to those 
queues with access permission for the users
\fIandreas\fP and \fIshannon\fP. The third command changes the queue
attribute \fIh_vmem\fP to 1 Gigabyte on queues residing on Linux machines
(see the
.M qconf 1
manual page for details on the \fI\-mattr\fP option and the
.M queue_conf 5
manual page on details of queue configuration entries).
.\"
.\"
.SH "ENVIRONMENTAL VARIABLES"
.\" 
.IP "\fBxxQS_NAME_Sxx_ROOT\fP" 1.5i
Specifies the location of the xxQS_NAMExx standard configuration
files.
.\"
.IP "\fBxxQS_NAME_Sxx_CELL\fP" 1.5i
If set, specifies the default xxQS_NAMExx cell. To address a xxQS_NAMExx
cell
.I qselect
uses (in the order of precedence):
.sp 1
.RS
.RS
The name of the cell specified in the environment 
variable xxQS_NAME_Sxx_CELL, if it is set.
.sp 1
The name of the default cell, i.e. \fBdefault\fP.
.sp 1
.RE
.RE
.\"
.IP "\fBxxQS_NAME_Sxx_DEBUG_LEVEL\fP" 1.5i
If set, specifies that debug information
should be written to stderr. In addition the level of
detail in which debug information is generated is defined.
.\"
.IP "\fBxxQS_NAME_Sxx_QMASTER_PORT\fP" 1.5i
If set, specifies the tcp port on which
.M xxqs_name_sxx_qmaster 8
is expected to listen for communication requests.
Most installations will use a services map entry for the
service "sge_qmaster" instead to define that port.
